1 Advanced Training Systems International Ejection/Egress System

2 2 Advanced Training Systems International INTRODUCTION This lesson will provide a working knowledge on using the ESCAPE SYSTEM of the TA-4.

3 3 Advanced Training Systems International OBJECTIVES Operational overview of ESCAPAC seat. Describe the preflight of the ejection seat. State normal ejection procedures. State manual bail-out procedures. State ground egress procedures.

4 4 Advanced Training Systems International EJECTION CONSIDERATIONS When do you eject? “...The timely ejection option, once selected becomes irrevocable. There must be no compromise of the principle of life through ejection by delaying the ejection decision too long...” 9 out of 12 ejection fatalities are out of the envelope.

5 5 Advanced Training Systems International MANDATORY EJECTION CONDITIONS Ejection may be necessary as result of fire, engine failure, structural damage, midair collision, or when the aircraft becomes uncontrollable.

6 6 Advanced Training Systems International ESCAPAC 1G-3 EJECTION SEAT Zero speed/Zero altitude seat. Back-type parachute. Rigid seat survival kit. TA-4 Sequence--canopy, rear seat, front seat 0.55 seconds after rear seat. Seat/man separation occurs within 1 second. Aneroid for parachute opening at 14,000’ (11,500’ - 15,000’ acceptable).

7 7 Advanced Training Systems International ESCAPAC 1G-3 CONTROLS Face Curtain Ejection Handle Ejection Control Safety Handle (Headknocker) Shoulder Harness Lock Lever Emergency Restraint (Harness) Release Handle Lower Ejection Handle

8 8 Advanced Training Systems International EJECTION SEAT SEPARATOR ROCKET Provides positive seat separation. Rocket thrust rotates and propels seat away to minimize probability of pilot/seat collision. Rocket fires 0.5 seconds after ejection initiated. Separator rocket armed by seat rocket catapult as seat leaves the rails. Seat Separator Rocket “Ear Burner”

9 9 Advanced Training Systems International SEQUENCE Pull upper or lower handle. Canopy jettisons. Inertia reel power retracts. Aft seat fires first to prevent blast injury from front seat seconds later, front seat fires. Emergency oxygen and beacon actuated. 0.3 second delay cartridge fires harness release. Seat/man separation at 0.5 seconds Ripcord pins 0.75 seconds.

10 10 Advanced Training Systems International SEAT SWITCH Switch located outboard, right console. The seat is electrically adjusted in the vertical plane by movement of the switch to the UP or DOWN position.

11 11 Advanced Training Systems International SHOULDER HARNESS LOCK LEVER Located on the left side of the seat bucket. Locks the inertial reel. Shoulder harness will not extend when lever in locked position. The unlocked position allows the harness to extend and retract as pilot moves (free movement). Inertial reel will lock automatically if aircraft subjected to 2.5g deceleration.

12 12 Advanced Training Systems International EMERGENCY RESTRAINT RELEASE HANDLE Mounted on the right side of the seat. Handle latch must be squeezed to pull handle and release the barometric parachute opener lanyard, shoulder harness and seat belt attachments. Allows the pilot to leave the cockpit with the parachute and survival kit still attached to the integrated torso harness. Labeled HARNESS RELEASE

13 13 Advanced Training Systems International FACE CURTAIN Housed in the headrest structure with the handle protruding. Screens the face from the wind blast during ejection. Handle serves as a control for ejecting the seat and aids in supporting and positioning the pilot during ejection.

14 14 Advanced Training Systems International LOWER EJECTION HANDLE Located on the forward side of the ejection seat between the pilot’s legs. Lower handle used to initiate the ejection sequence when the face curtain is not desirable or possible. A pull force of not more than 60 pounds is required to initiate ejection with lower handle.

15 15 Advanced Training Systems International HEADKNOCKER EJECTION CONTROL SAFETY HANDLE located between two rubber pads on the upper forward area of headrest. Functions as an ejection seat safety lock when in the down position. Safety lock must be manually depressed to raise headknocker to the up position.

16 16 Advanced Training Systems International EJECTION SEAT CONTROL SELECTOR Located in the forward cockpit on the bulkhead aft of the left console. Two position valve set prior to flight. UP position: Front seat pilot can eject both seats. Rear seat pilot can eject rear seat only. DOWN position: Both seats ejected regardless of which pilot initiates ejection. “UP FOR SOLO, DOWN FOR DUAL”

17 17 Advanced Training Systems International NES-12 PARACHUTE PACK 28’ flat circular canopy. Ballistic spreader gun opens chute after 0.75 second delay as long as crewman below 14,000’. External pilot chute orients pilot position for effective deployment of parachute canopy. 4-line release system provides parachute stabilization with minimal parachute steering capabilities.

18 18 Advanced Training Systems International EJECTION SEAT STABILIZATION (DART) Counteracts the adverse effects of aerodynamics and seat system center of gravity. Provides consistent and predictable trajectory during the rocket burning phase. System installed on the underside of the seat bucket.

19 19 Advanced Training Systems International Rigid Seat Survival Kit. Contains emergency oxygen supply, survival equipment, and emergency beacon. RSSK-8 SURVIVAL KIT

20 20 Advanced Training Systems International EJECTION SEAT PREFLIGHT

21 21 Advanced Training Systems International EJECTION SEAT PREFLIGHT (CON’T)

23 23 Advanced Training Systems International EJECTION INTIATION - FACE CURTAIN

24 24 Advanced Training Systems International EJECTION INTIATION - FACE CURTAIN (CON’T)

25 25 Advanced Training Systems International EJECTION INTIATION - FACE CURTAIN (CON’T)

26 26 Advanced Training Systems International EJECTION INTIATION - LOWER HANDLE

27 27 Advanced Training Systems International EJECTION INTIATION - LOWER HANDLE (CON’T)

28 28 Advanced Training Systems International CONTROLLED EJECTION PROCEDURES

29 29 Advanced Training Systems International CONTROLLED EJECTION PROCEDURES (CON’T)

30 30 Advanced Training Systems International MANUAL BAILOUT PROCEDURES 1.Pull green ring on seat pan for emergency oxygen. 2.Disconnect console oxygen and antiblackout hose. 3.Select RAM. 4.Jettison canopy. 5.Pull emergency restraint release handle. 6.Lean forward to clear parachute past headset. 7.Trim aircraft nose down. 8.Apply back pressure to stick. 9.Position arms against body and let stick snap forward. 10.When clear of aircraft and below approximately 14,000’, pull parachute ripcord. 11.As time permits, perform post- ejection procedures.

31 31 Advanced Training Systems International POST EJECTION CONSIDERATIONS If either the harness release or automatic barometric PARACHUTE actuator cartridge fails to function properly, automatic SEAT separation and/or PARACHUTE deployment may not occur. Therefore, during any low altitude ejection, the pilot should attempt to “BEAT THE SEAT” by manually pulling the EMERGENCY RESTRAINT RELEASE HANDLE and then the PARACHUTE RIPCORD immediately after ejection. High altitude. Low altitude. Over land. IROK Over water.

32 32 Advanced Training Systems International MANUAL SEAT/MAN SEPARATION

33 33 Advanced Training Systems International MANUAL SEAT/MAN SEPARATION (CON’T)

34 34 Advanced Training Systems International GROUND EGRESS - WITHOUT PARACHUTE When electing to exit the aircraft without PARACHUTE and SURVIVAL KIT, the following procedures should be followed: 1.Pull CANOPY JETTISON HANDLE. 2.Unfasten the four (two upper Koch fittings, two lower) PARACHUTE HARNESS FITTINGS. 3.Disconnect OXYGEN HOSE 4.If time permits, safety the ejection controls by pulling the SAFETY HANDLE on the pilot headrest to the “DOWN” position. This will preclude inadvertent ejection of the SEAT. 5.Exit from aircraft.

35 35 Advanced Training Systems International REVIEW 0/0 Seat (study seat envelope charts). High altitude (time permitting) - controlled ejection procedures with use of face curtain. Low altitude - immediate ejection with use of lower handle, “try and beat the seat.” Body positioning critical to minimizing injury. IROK Decide on preferred ground egress method.
